Priced at $4.99 on PC and $2.99 in iTunes, the side-scrolling single-player jetpack shooter offers online leaderboards and an exclusive "secret ending" over the downloadable Nintendo DSi edition that hit in January 2010.

The entire affair is meant to promote the recent arrival of Airtight's full-fledged jetpack shooter Dark Void, with the elaborate fictional history claiming that Dark Void Zero represents a long-lost Capcom project archived by none other than Jimmy Fallon.
